An Efficient Guaranteed Bandwidth And Balancing Mechanism For High Speed Mans, Venediktos Hadjisavvas Oct 1993

An Efficient Guaranteed Bandwidth And Balancing Mechanism For High Speed Mans, Venediktos Hadjisavvas

Theses

The Distributed Queue Dual Bus (DQDB) has become the IEEE 802.6 stan-dard for Metropolitan Area Networks (MANs). The main advantage of DQDB is that its throughput performance is not affected by the network parameters such as size, number of connected stations, or channel bandwidth. Its main drawback is that the location of the stations on the bus strongly affects their performance. For this reason a Bandwidth Balancing Mechanism (BBM_DQDB) has been proposed and included in the 802.6 standard that can provide the requested bandwidth by the lightly loaded stations and evenly distribute the remaining bandwidth among the overloaded stations. The …

A Parallel Processing Architecture For Dqdb Protocol Implementation, Nilesh Vinubhai Gandhi

Theses

The high bandwidth transmission links, which have been provided by the advances of Fiber Optics Technology, reduce drastically the packet transmission times and place new demands on the nodal protocol processing. Segmentation and reassembly of packets, computation of checksums, introduction of source and destination addresses, etc., must be performed extremely fast in order to prevent node processing from becoming the bottleneck of the transmission. Parallel processing enables the execution of the previous tasks on multiple packets simultaneously and therefore has the potential of addressing the issue of fast node processing successfully. In this thesis we focus on the Medium Access …
